Underdog Strikes Gold: Modest $300 Rig Defies Astronomical 149 Million-to-1 Odds to Claim $232,000 Bitcoin Jackpot

In a stunning upset, a lone miner using a modest Canaan Avalon Nano 3S device, capable of processing 6.68 terahashes per second, defied staggering odds of 1 in 149 million to claim Bitcoin block 951771. This remarkable feat, achieved on May 30, 2026, at 4:27:23 p.m. ET, yielded a substantial reward of approximately $232,000.

The victorious miner, operating through the Braiins Solo pool, reaped a block reward of 3.1404 BTC, comprising a 3.125 BTC subsidy and $1,137 in transaction fees. This windfall was made possible by the miner's participation in a pool designed specifically for solo miners, which enables them to retain the full reward in the event of a successful block discovery.

Notably, the Canaan Avalon Nano 3S, a compact and energy-efficient device consuming a mere 140 watts of power, is marketed for home use and can even double as a space heater. With a retail price of around $250-$300, this device is an attractive option for hobbyists and home miners. Its specifications, including a quiet operation of 33-40 decibels and Wi-Fi or Ethernet connectivity, make it an ideal choice for those seeking a low-maintenance mining solution.

The mathematical probability of this specific machine discovering a block is approximately 6.72 in a billion, or 1 in 148,904,370. Considering the Bitcoin network's implied hashrate of around 1,000 exahash per second (EH/s) or 1 zettahash per second (ZH/s) at the time, the odds of success were indeed slim. In fact, if this rig were to operate continuously, it would take an estimated 2,831 years to find a single block.

The winning miner reportedly operates a small fleet of devices, including two Avalon Mini 3 units and 12 Avalon Nano 3S units, totaling roughly 147 TH/s. While the odds of success improve to approximately 1 in 6.7 million per block at the fleet level, with an expected win every 127 years, the block announcement credited a single Nano 3S worker as the machine responsible for finding block 951771.

This remarkable achievement is not an isolated incident, as roughly two dozen solo blocks have been discovered in the past 12 months. Other notable examples include a 4.8 TH/s Nerdqaxe++ machine winning a block worth around $224,000 in April 2026, as well as successes by Bitaxe and Futurebit Apollo miners. The renewed interest in solo and hybrid mining services has led to the emergence of various platforms catering to home miners and hobbyists, including Futurebit Solo, CKPool Solo, Public Pool, Braiins Solo, Parasite, and Nicehash Easymining.

The significance of this event lies in its demonstration that the Bitcoin protocol remains accessible to individual miners, regardless of their investment size. The fact that a single home miner using a consumer-grade device can still achieve success serves as a testament to the protocol's design and has sparked widespread enthusiasm among hobbyists and mining communities. As the mining landscape continues to evolve, this remarkable win has rekindled interest in solo bitcoin mining, highlighting its potential as a viable, albeit long-shot, pursuit.
